The Nuobell Story

Born in Sweden, Nuobell reimagined strength training with its sleek, space-saving adjustable dumbbells, a product that blended Scandinavian design with serious performance. Beloved in Europe, the brand set its sights on the US, launching on Amazon with high hopes but little experience.

Just two months in, they faced reseller crowding, weak A+ content, and virtually no reviews, making it hard to stand out. Leading the charge were CEO Per Svenberg and business owner Stephanie Probasco, determined to turn early traction into dominance.

Summary

In under a year on Amazon US, Nuobell moved from a crowded, reseller-heavy landscape to one of the best in its category.

Starting just two months post-launch, SellerApp re-architected its advertising, sharpened keyword focus, upgraded A+ content, and used AI to make thousands of smart bidding decisions automatically.

Thus, Ad revenue jumped to $512,145, total campaign-period sales reached $775,895, ACoS fell to 11.15% (from as high as ~42–48%), and the Hero SKU earned the Amazon’s Choice badge. Monthly revenue goes up to 100k to 180k, depending on the season.

In August 2025, total sales soared to a monumental $1,364,325, which means a 38x growth in total sales from the time Nuobell joined SellerApp.

Challenges Nuobell Faced Before SellerApp

When Nuobell first stepped into the US Amazon market, it faced a series of hurdles that threatened to stall its growth.

Reseller crowding & zero differentiation
Multiple sellers were listing the same adjustable dumbbells, making it difficult for shoppers to identify the authentic Nuobell brand. This diluted brand equity, confused customers, and created intense price-based competition, preventing Nuobell from establishing a unique presence.

Non-uniform sales
Revenue was inconsistent, with unpredictable spikes and drops. Without a repeatable system for ads, content, and conversion optimization, Nuobell struggled to create a stable sales baseline.

Early-stage Amazon presence
The brand was only 60 days into selling on Amazon. Limited data and visibility, coupled with low brand trust, made it challenging to optimize campaigns or compete effectively with established players.

Content gaps
A+ content was incomplete or underperforming, and one ASIN lacked A+ entirely. This reduced shopper engagement, lowered conversion rates, and limited organic ranking potential, since Amazon rewards informative and visually appealing product pages.

No reviews at join
With zero social proof, customers were hesitant to purchase. Reviews are critical on Amazon for credibility, conversion, and ranking, so this lack created a barrier to growth.

Manual ad management
Ads were being managed manually, which was time-consuming and inefficient. Constant tweaks without strategic insights led to wasted effort and suboptimal campaign performance.

Inefficient ads & high ACoS
Ads had ACoS of 42–48% despite manual optimization. Poor targeting, absence of negative keywords, and no insight into top-performing search terms meant money was spent on low-converting traffic.

Inadequate performance of tools
TExisting tools like Helium 10 were in place, but they weren’t translating into actionable improvements for Amazon Ads. Nuobell lacked a cohesive system that connected analytics to campaign performance.

Amazon’s algorithm rewards relevance, conversion consistency, and shopper engagement. Without differentiated content, authentic reviews, and precise ad targeting, Nuobell was paying for traffic it couldn’t convert, while resellers captured valuable brand search visibility and dominated customer attention.

SellerApp’s Solution that Skyrocketed Nuobel’s Performance

1. Full-Funnel PPC Strategy & Execution

We also created a granular campaign taxonomy:

Nuobell’s initial campaigns were mostly auto-generated, meaning the ads weren’t strategically segmented. Our Amazon PPC advertisers rebuilt its campaigns across Sponsored Products (SP), Sponsored Brands (SB), and Sponsored Display (SD) to intentionally cover the full purchase funnel:

  • Brand campaigns: Capture existing demand efficiently, leveraging low CPC and high intent.
  • Core category campaigns: Scale across relevant search terms like “adjustable dumbbells” and close variants to capture active buyers.
  • Competitor campaigns: Target rival brand terms to intercept shoppers mid-decision.
  • Permutation sets in SB/SD campaigns: Broaden reach across multiple combinations of keywords and product sets to capture qualified traffic.


Funnel coverage stabilizes sales by ensuring that the brand is visible at every stage of the buyer journey. Granularity allows precise budget allocation, so money flows to high-performing, high-potential segments instead of being wasted across broad, low-converting traffic.

2. AI Automation (Bids & Budgets)

SellerApp team enabled AI-driven bid automation to continuously adjust CPCs based on performance metrics. This leveraged Nuobell’s high Average Order Value (AOV) against low CPC opportunities, allowing campaigns to scale impressions efficiently without overspending. Automation handled real-time bid tuning, freeing the team to focus on strategic growth initiatives and campaign expansion.

At Nuobell’s price point, small bid misalignments can lead to disproportionately high costs. Hour-by-hour adjustments by AI ensured maximized efficiency and reduced wasted ad spend. It also saved ~12 hours per week for strategic, higher-leverage work, making human effort more impactful.

3. Search Term Analysis, SQP-Led Optimizations & Negatives

Using Search Query Performance (SQP) insights, our PPC experts identified high-value search terms that were driving conversions and eliminated unproductive queries through negative targeting. We also performed aggressive bid rebalancing by query class (brand, core, competitor, long-tail) to ensure spend matched potential.

Lowering ACoS starts with stopping spend on irrelevant clicks while increasing investment where returns are strong. This ensures every ad dollar drives measurable performance and that campaigns focus on qualified, high-converting traffic.

4. Listing Optimization & A+ Content Uplift

Our PPC experts revamped Nuobell’s A+ content to highlight the brand story, engineering, and product benefits in a way resellers could not replicate. Titles, bullets, and images were optimized around purchase-deciding factors such as weight ranges, grip/lock mechanisms, compact design, and warranty assurances.

Optimized content improves relevance, leading to lower CTR, further making a higher conversion rate (CVR) possible. It signals to Amazon’s algorithm that the listing is high-quality, increasing impressions while lowering CPC. Strong content also differentiates the brand in a crowded market, increasing shopper trust and purchase confidence.

5. Keyword Research, Rank Tracking & Competitor Intelligence

We conducted continuous keyword research and rank tracking for core and long-tail queries, adjusting budgets where high-ranking keywords correlated with strong CVR. Competitor targeting was used to capture share-of-voice on rival product pages, intercepting shoppers in the decision phase.

Ranking momentum plus strategic competitor conquesting compounds over time, improving organic visibility and reducing reliance on paid ads. It ensures that the brand benefits from both paid efficiency and long-term organic growth, creating a sustainable competitive advantage.

6. Custom Dashboards & Strategic Consultations

SellerApp built live dashboards for budget pacing, search term ROAS, and rank movements. Bi-weekly strategic consultations allowed the team to make data-driven, high-confidence decisions quickly.

When both the brand and agency share real-time insights, decisions are faster, more precise, and aligned. Transparency reduces guesswork, empowers agile optimization, and ensures every strategic adjustment is rooted in measurable performance.
